Microwave Data Systems (MDS) is a world leader in wireless data networking solutions with applications in the SCADA, telemetry, telecommunications, and on-line transaction processing markets. As a leader in advanced traffic control, the City of Colorado Springs uses MDS Spread Spectrum radios at many of its intersection controllers.

The City of Colorado Springs chose Microwave Data Systems (MDS) to solve their communication problems in traffic management and high network infrastructure costs. Earlier, MDS also successfully solved their water system problems. MDS' radios reliability and lower costs made the difference.

Problem

Reliability-The Key Element
The cornerstone of any successful network is reliable communication-and it is especially important where traffic safety is concerned.

Solution
Based on engineering specifications and a long-term relationship with Microwave Data Systems, our MDS transceivers were chosen for use at over 200 sites in the network. The transceivers use advanced Spread Spectrum technology and operate at 900 MHz frequencies.

The system contains a remote network of upgraded intersection controllers, weather stations, video cameras, loop detectors, and carbon monoxide monitors. These stations gather critical information about road conditions and forward their data to the Colorado Springs Traffic Control Center. Traffic Analysts working at the Center can view the data and immediately respond to traffic problems with the appropriate actions. Corrective measures may include adjustments to signal timing, notification of emergency services, or posting of detour and hazard notices on variable message signs.

In an interview with the Principal Traffic Engineer for the City of Colorado Springs, John C. Merritt, pointed out that reliability and cost effectiveness were the main reasons for approving MDS transceivers. He also cited the solid track record of MDS radios installed by another city division - the Colorado Springs Water Department.

John added that the city was impressed with the signal-capturing ability of the MDS transceivers. Interference rejection was another important consideration.

"The MDS transceiver allowed us to consistently lock-in at distances over 15 miles using only a hand-held test antenna. Products from other manufacturers could not equal this performance."

Wireless - A Reliable Alternative
With leased telephone lines costing the city over $50,000 per year, a less expensive MDS wireless system came as a welcome change to Colorado Springs. With an MDS radio based system, the equipment is owned and controlled directly by the city, and there are no monthly charges for its use. If a problem should occur, it can be corrected immediately - with no waiting for the telephone company's repair service.

License-free MDS radio was another cost benefit for Colorado Springs. The radios could be installed and put on the air immediately without the added expense and paperwork associated with frequency coordination and licensing.

Engineered Solutions from MDS
The Colorado Springs application is one example of how MDS products are being used to solve today's communications problems. Whether your application calls for traffic control, utilities management, or any other remote data operation, the reliability of MDS products makes them a solid alternative to expensive leased lines.
